 The `uri` attribute is an instance of ParseResult from the standard library's `urlparse` module.
 
-## referers.json

-Unlike the other ports, the Python version of referer-parser uses a `referers.json` file, generated from the main `referers.yml` file. This is for two reasons:
-
-1. Python's standard library includes a JSON parser but not a YAML parser
-2. Loading from JSON in Python is significantly faster than loading from YAML
-
-To support the `referers.json` file, the distribution process for Python looks like this:
-
-    $ ./sync_yaml.sh
-    $ cd python/referer_parser && python build_json.py
-    $ cd .. && python setup.py sdist bdist_wininst upload
